Recommendations Database

GAO’s recommendations database contains report recommendations that still need to be addressed. GAO’s priority recommendations are those that we believe warrant priority attention. We sent letters to the heads of key departments and agencies, urging them to continue focusing on these issues. Below you can search only priority recommendations, or search all recommendations.

Our recommendations help congressional and agency leaders prepare for appropriations and oversight activities, as well as help improve government operations. Moreover, when implemented, some of our priority recommendations can save large amounts of money, help Congress make decisions on major issues, and substantially improve or transform major government programs or agencies, among other benefits.

As of October 25, 2020, there are 4812 open recommendations, of which 473 are priority recommendations. Recommendations remain open until they are designated as Closed-implemented or Closed-not implemented.

Nuclear Cleanup: Actions Needed to Improve Cleanup Efforts at DOE's Three Former Gaseous Diffusion Plants
GAO-20-63, Dec 17, 2019
Director: David C. Trimble
Phone: (202) 512-3841

5 open recommendations

Recommendation: The Secretary of Energy should direct the Assistant Secretary of the Office of Environmental Management to take steps to manage the three GDPs as an integrated program and follow relevant program management leading practices (developing a GDP-wide program management plan; an integrated master schedule; and a reliable, integrated, comprehensive life-cycle cost estimate.) (Recommendation 1)

Agency: Department of Energy: Office of the Secretary
Status: Open

Comments: In June 2020, DOE officials told us that its Office of Environmental Management (EM) Portsmouth/Paducah Project Office (PPPO) is in the process of developing a program management master plan, to include site-integrated master schedules and life-cycle cost estimates, for the Portsmouth and Paducah gaseous diffusion plants (GDPs). Officials stated that the plan will incorporate program management leading practices as appropriate. According to DOE officials, EM will direct PPPO to use actual collected cost and schedule information for integration of relevant lessons learned from ETTP cleanup into integrated program plans, schedules, and estimates. DOE officials estimated that this effort would be completed by December 31, 2020.
Recommendation: The Secretary of Energy should direct the Assistant Secretary of the Office of Environmental Management to track consistent and detailed expenditure information on cleanup activities across the three GDPs. (Recommendation 2)

Agency: Department of Energy: Office of the Secretary
Status: Open

Comments: In June 2020, DOE officials told us that its Office of Environmental Management (EM) is assessing and identifying an appropriate mechanism for tracking expenditures for both the Portsmouth and Paducah GDP sites, using a standardized approach with an Earned Value Management System (EVMS) reporting on, at a minimum, an annual basis. According to DOE officials, PPPO is in the process of using the ETTP data as a basis of comparison for contractor estimates and assessing the potential development of cost estimating tools for independent cost estimating. DOE officials estimated that this effort would be completed by December 31, 2020.
Recommendation: The Secretary of Energy should direct the Assistant Secretary of the Office of Environmental Management to ensure the site-specific life-cycle cost estimates for the cleanup of each of the GDPs fully incorporate best practices for cost estimation. (Recommendation 3)

Agency: Department of Energy: Office of the Secretary
Status: Open

Comments: In June 2020, DOE officials told us that its Office of Environmental Management (EM) has directed the Portsmouth and Paducah GDP sites to review and incorporate the practices from GAO's Cost Estimating Guide (GAO-20-195G), as appropriate, into the next revision of each site's life-cycle cost baselines. According to DOE officials, Oak Ridge is in the process of procuring a follow-on cleanup contract, which includes the scope to complete the cleanup of ETTP. According to DOE officials, given that the cleanup of the ETTP GDP is nearly complete, the baseline for the entire ETTP GDP will not be included in the life cycle cost estimate review. Officials stated the remaining scope of work for the ETTP GDP will, however, become part of the performance baseline for the next Oak Ridge cleanup contractor. DOE officials estimated that this effort would be completed by December 31, 2020.
Recommendation: The Secretary of Energy should direct the Assistant Secretary of the Office of Environmental Management to work—in conjunction with EPA and Kentucky and Tennessee state regulators—with an independent, third-party facilitator to help resolve disagreements over cleanup priorities, cleanup remedies, and cost estimation assumptions. (Recommendation 4)

Agency: Department of Energy: Office of the Secretary
Status: Open

Comments: In June 2020, DOE officials told us that its Office of Environmental Management (EM) has incorporated the use of an independent facilitator on a case-by-case basis to help resolve any disagreements, in conjunction with the Environmental Protection Agency (EPA), and Kentucky and Tennessee state regulators over cleanup priorities, remedies, and cost estimation assumptions. Officials stated that most recently, the Paducah GDP site used an independent facilitator to resolve disagreements with EPA Region IV and Kentucky state regulators. According to DOE officials, in the future, EM will continue the use of an independent facilitator, as deemed appropriate. DOE officials estimated that this effort would be completed by December 31, 2020.
Recommendation: The Secretary of Energy should regularly report on the status of the D&D Fund and cleanup efforts at the three GDPs with current information that contains details on challenges in reaching agreement with regulators and a clear scope of work. (Recommendation 5)

Agency: Department of Energy: Office of the Secretary
Status: Open

Comments: In June 2020, DOE officials told us that its Office of Environmental Management (EM) has prepared the triennial Uranium Enrichment Decontamination and Decommissioning Fund Report, providing accomplishments through fiscal year 2019 and disclosing the most recent environmental liability estimate associated with remaining challenges and scope of cleanup at the GDPs. Officials stated that the report is being circulated for approval. DOE officials estimated that this effort would be completed by December 31, 2020.
Nuclear Weapons: NNSA Should Clarify Long-Term Uranium Enrichment Mission Needs and Improve Technology Cost Estimates
GAO-18-126, Feb 16, 2018
Director: Allison Bawden

Recommendation: The NNSA Administrator should revise the scope of the mission need statement to clarify which mission need it seeks to achieve and, as appropriate, adjust the range of options considered in the analysis of alternatives process. (Recommendation 1)

Agency: Department of Energy: National Nuclear Security Administration
Status: Open

Comments: NNSA disagreed with our recommendation and has not taken steps to implement it. In August 2019, GAO requested an update on the status of the small centrifuge project at Oak Ridge since NNSA officials indicated in May 2019 that the status of the small centrifuge project will impact NNSA's ability to complete the analysis of alternatives (AOA) process by December 2019, as originally planned. Early in calendar year 2020, NNSA announced that completion of the AOA would be delayed to the end of fiscal year 2020. In September 2020, NNSA stated that the COVID-19 pandemic had further delayed the AOA and that the agency had not determined a revised target date for completion. We will continue monitoring the AOA process and will review the AOA once it is completed to determine whether we can close this recommendation at that time.
Recommendation: The NNSA Administrator should--following clarification of the scope of the mission need statement--ensure that the agency's cost estimates for whichever options it considers going forward are aligned with the scope of the mission need that the enrichment capability is intended to fulfill and that they are developed consistent with best practices. (Recommendation 2)
